1 The Next Generation Humidity Reference Standard GE's Optica Series chilled mirror hygrometers offer National Institute of Standards and Technologies (NIST) _ traceable humidity, temperature and pressure measurements for the connected generation. Now data is accessible from anywhere, any time, from within a browser over the Internet or from your intranet. Optica Measures Temperature Relative humidity (% RH) Dew/frost point (Td) Absolute humidity (m/v) Mass mixing ratio (m/m) Volume mixing ratio (v/v) Wet bulb (Tw) Enthalpy (h) Water vapor pressure (e) Pressure Alarm relays Analog outputs Fundamental dew point measurement is a primary measurement used as a transfer standard for calibrating other humidity instruments and sensors. Chilled mirrors are also the sensors of choice when process and laboratory measurements call for high precision without long term drift. Optica may be used with five, fully interchangeable chilled mirror sensors to provide a measurement range from -112 F to 185 F (-80 C to 85 C) dew point with 0.36 F (0.2 C) or better accuracy. Inputs for a 100 S RTD and silicon-based piezoresistive pressure transducer ensure precision measurements, which are used to convert the dew point to any metric, English or user-defined unit of humidity measure. Optica Optica is a General Eastern product. General Eastern has joined other GE high-technology sensing businesses under a new name _ GE Industrial,. g

Users select readout display, strip chart, analog output scale, digital communications, self-diagnostics, cleaning and data logging with intuitive pull-down menus. Setup values can be saved in memory and loaded anytime, either locally or from anywhere via the Ethernet port. Heat exchanger and refrigerant coil calorimeters Thermal processing/heat treating Semiconductor manufacturing Storage areas Pharmaceutical validation chambers Engine test cells and emissions testing Aircraft engines and turbines Functionality The Optica simultaneously measures dew point, temperature and pressure. The analyzer is equipped with programmable math functions to produce custom units. In, exp +, -, x and / functions enable derived engineering units to be displayed, recorded and transmitted to data acquisition systems. The analyzer input channel is a standard 4 to 20 ma/0 to 5 VDC input, so the Optica can be connected to any type of process transmitter and be configured to display engineering units. Plug and play setup is easily accomplished with standard connectors for power, sensor and analog outputs. In the Lab or on the Plant Floor Calibration labs Process control Clean rooms Environmental test chambers Precision HVAC monitoring and control Fuel cells Chilled Sensors Theory of Operation GE s chilled mirror hygrometers are used in standards and metrology labs as well as in industrial applications where precise and repeatable humidity measurement and control is required. The inherent accuracy and long term stability provides many advantages over other types of humidity measurement technologies. Chilled mirrors fundamentally measure the dew or frost point temperature directly by controlling a reflective surface to an equilibrium temperature between dew/frost formation and evaporation, and precisely measuring the temperature of the mirror at this point.

3 GE's chilled mirrors consist of a small polished hexagonal rhodium, or platinum mirror attached to thermoelectric cooling module (TEC). The Optica analyzer's servo controller applies current to the TEC, which causes the mirror to cool. The mirror is illuminated with a regulated Gas emitter, which transmits light in the infrared spectrum. The light reflected by the mirror is received by a photodetector. When water vapor condenses on the mirror as water or frost (ice crystals), the light received by the photodetector is reduced due to scattering. This results in the servo controller reducing the power causing the mirror to slightly warm. The Optica's control system will modulate the amount of current flowing though the TEC to maintain a temperature where the rate of condensation and evaporation of water molecules and the mass of water on the mirror is constant. The resulting temperature of the mirror is then, fundamentally by definition, equal to the dew or frost point temperature. A precision four-wire platinum RTD imbedded in the mirror measures the temperature. The accuracy of the dew point measurement has been validated to an accuracy of ±0.36 F (±0.2 C) dew/frost point. The precision can also be enhanced to ±0.27 F (±0.15 C) dew/frost point. Dry bulb temperature is measured with a precise four-wire 100 S platinum RTD and pressure is measured with a piezoresistive silicon pressure transducer. The dew/frost point and dry bulb RTD resistance signals are conditioned and amplified by the Optica monitor to display and transmit dew/frost point and temperature. The pressure sensor transmits an amplified 4 to 20 ma signal that is powered by the Optica. The cardinal measurements of dew/frost point, dry bulb temperature and pressure are used to calculate other humidity parameters such as relative humidity, wet bulb, mass mixing ratio, volumetric mixing ratio, absolute humidity, enthalpy and water vapor pressure values using psychometric equations. The RTD sensor is imbedded in the chilled mirror and never comes in contact with the process or test environment. The wetted parts consist of the platinum or rhodium mirror, a stainless steel or mylar vapor barrier and epoxy sealant. The net result is drift-free humidity measurement designed to maintain accuracy specifications for many years. Chilled mirrors require a nominal flow rate across the mirror to achieve the optimal dew/frost formation and response time. The sensor should either be installed in a duct with moving air or be equipped with a sampling pump. The optimum flow rate is 0.5 to 5 SCFH (0.25 to 2.5 L/min). GE provides sampling systems to temperature condition, regulate the pressure and filter process air prior to reaching the chilled mirror. Our application engineers will discuss your application in detail and provide a recommendation for the system best suited to your needs. LED regulation Precision four-wire PRTD Light emitting diodes Photo detectors Optical balance Thermoelectric cooling module Rhodium or platinum mirror OP AMP Thermoelectric heat pump control Self Cleaning and Digital Control Gas flow For environments where physical contaminants such as dust, oil mist and pollen are present, the use of a sampling system with a filter media is recommended. The filter media must be hydrophobic so as to not absorb or release water vapor into the test stream. Over time the mirror can be etched or pitted by particulate, altering the light scattering characteristics. GE mirrors are field replaceable. The standard rhodium mirror may be upgraded to platinum for industrial applications. GE developed a patented contamination compensation scheme called PACER (Program Automatic Error Reduction). The PACER cycle may be initiated manually or by programming a timed cycle. The cycle starts by capturing the data (during the PACER cycle a constant value is transmitted) and cooling the mirror well below the dew point such that a thick dew layer forms on the mirror. The mirror is then rapidly heated. During the heating a significant amount of soluble and some non-soluble contamination is flash evaporated. The contamination left on the mirror tends to aggregate in dry islands or spots (much like a glass that comes out of a dishwasher). This process leaves approximately 85% of the mirror clean. The light signal received by the photodetector is compared against a reference LED/photodetector and the two signals are "balanced," effectively negating the effect of the residual contamination left on the mirror. The PACER cycle works very well, but eventually manual cleaning may be required. All of GE's chilled mirrors are accessible for

4 manual cleaning. Cleaning is a simple process consisting of wiping the mirror with a cotton swab wetted with cleaning solution or distilled water. (Distilled water is recommended as the final cleaning agent.) GE developed Digiloop control to overcome the limitations of traditional analog PID (Proportional Integral and Derivative) control. Analog temperature control produces oscillations particularly at high or trace humidity levels. It is difficult to apply self-tuning or PID constants to analog control loops, which are over damped or under damped. Digiloop utilizes digital sampling and feed-forward control by taking time-based samples when the dew point is within a predetermined proportional band. By recording the oscillations, the digital control effectively predicts the magnitude of change and adjusts the current to the thermoelectric cooling module, which steps the mirror temperature in 0.09 F (0.05 C) increments. This results in a significantly improved control and dew point precision.
